Boston Scientific M00518261 Interject Injection Therapy Needle - 25G x 6mm - 200cm 5 Box

Boston Scientific Interject | Injection Therapy Needle | M00518261

The Boston Scientific Interject (M00518261) is a specialized endoscopic needle engineered for the 2026 standard of care in gastrointestinal hemostasis and lesion management. This 25-gauge system is specifically designed to perform in the most challenging anatomical environments. Featuring a unique star-shaped inner catheter, the Interject ensures smooth, reliable needle deployment even when the endoscope is acutely retroflexed or positioned in tortuous anatomy where standard needles often fail to actuate.

With its 6mm extension length, this needle provides the necessary depth for effective submucosal lifting and targeted delivery of sclerosing agents or vasoconstrictors.

Key Performance Features

• Star-Shaped Inner Catheter: This patented design reduces the surface contact and friction between the needle and the outer sheath. It ensures that the needle extends and retracts fluidly, even when the scope is in a tight "U-turn" or retroflexed position.

• 25 Gauge Ultra-Fine Needle: The thin-wall needle design allows for precise delivery of medications with minimal secondary tissue trauma, which is vital when treating delicate esophageal or gastric mucosa.

• 6mm Needle Extension: The 6mm length offers a deeper reach than standard 4mm needles, allowing for more effective saline "lifting" of lesions during EMR or deeper penetration into vascular structures for epinephrine delivery.

• Kink-Resistant Pushable Sheath: The outer sheath is constructed to provide excellent pushability. It advances through the biopsy channel without "bunching," ensuring the needle arrives at the distal end of the scope ready for immediate use.

• Locking Hub Mechanism: A secure locking system prevents accidental deployment of the needle while it is being passed through the scope, protecting the expensive working channel from internal damage.

Clinical Advantages

• Superior Hemostasis: Ideal for the rapid delivery of epinephrine or other vasoconstrictors to stop active ulcer bleeds or non-variceal hemorrhages.

• EMR/Polypectomy Preparation: Provides the control needed to create a safe submucosal saline "cushion," lifting lesions away from the muscularis propria to reduce the risk of perforation during resection.

• Enhanced Visibility: The contrast-enhanced sheath ensures the clinician can track the needle’s position clearly via the endoscopic monitor or under fluoroscopy.

Ideal Applications

• Gastrointestinal Endoscopy (Upper and Lower): Controlling active bleeds in the stomach, duodenum, or colon.

• Endoscopic Mucosal Resection (EMR): Submucosal injection for safe lesion lifting.
